Bradley suffered the injury in the Eagles' Sunday night practice, a source told the radio station, but was able to walk off the field after tackling another player.

Bradley, a third-round pick in 2007, had 151 tackles in his first full season as a starter last year. He's the primary signal caller on a defense that already lost veteran safety Brian Dawkins in free agency.

The Eagles had invited fans to attend the practice Sunday, known as "Flight Night," at Lincoln Financial Field.

BETHLEHEM, Pa. -- Philadelphia Eagles defensive end Juqua Parker has been arrested on a marijuana possession charge in northeast Pennsylvania.

Lower Saucon Township police said Parker was a passenger in a vehicle that was stopped for a traffic violation at 12:33 a.m. ET Wednesday near the Eagles' training camp at Lehigh University.

Parker was found to be in possession of "a small amount of marijuana" and was taken to Northampton County Prison, police said. Parker was released after posting $1,000 bail later Wednesday morning, a prison official said.

Eagles coach Andy Reid said he was aware of the incident.

"It's in the law's hands right now. As time goes on, I'll know more," Reid said.

They have alot of talent on Offense...I like the Maclin pickup. We will see. the division surprises me yearly on who rises up and who has trouble. Last year the Boys struggled. The Eagles struggled after making playoff runs. I am glad the Boys are considered 3rd in the division. Just play and see what happens instead of being a frontrunner.

The team made a flurry of roster moves, including the signing of defensive end Jason Babin, a former first-round pick by the Houston Texans. The Eagles also signed veteran middle linebacker Matt Wilhelm, who was recently released by the San Diego Chargers, creating more competition for Joe Mays and Omar Gaither. Both veterans received one-year deals.

To make room for Maclin, Babin and Wilhelm, the Eagles released defensive tackle Jervonte Jackson, cornerback Courtney Robinson, and wide receiver Marcus Thigpen.

Babin, 29, was a first-round pick in 2004 after setting a school record for career sacks at Western Michigan. He started 16 games and had four sacks as a rookie and registered a total of 13 sacks in three seasons with Houston before being traded to Seattle in 2007. He had two sacks in seven games with Kansas City last year, but was unemployed when the call came from the Eagles .

"I love the opportunity to be here and play Football," Babin said. "I've been trying to find the right home. I played end in college, and [the Texans] put me at outside linebacker. I always wanted to get back to defensive end, and . . . with K.C. last year, it was kind of a first step to doing that."
